Cut butter and coconut oil into cubes. Knead fat, flour and salt to a crumbly mass. Add about 4 tablespoons of ice-cold water and knead everything into a smooth shortcrust pastry. Cover and refrigerate for about 1 hour
In the meantime cut the peaches into slices. Roll out the shortcrust pastry on a lightly floured work surface until round (approx. 32 cm Ø) and place in a greased tart tin (28 cm Ø). Prick the pastry base several times with a fork. Place peach slices in the mould. Bake in the preheated oven (electric cooker: 225 ° C/ gas: level 4) for about 30 minutes
Warm the jam, pass it through a sieve and spread it thickly on the tart. Grill for about 2 minutes or bake for another 10 minutes at 225 °C. Sprinkle the tarte with diabetic sweetness and serve hot or cold with whipped cream
